Specification of Letters Patent.

Patented Jan. 26, 1909.

Application filed October 22, 1908. Serial No. 459,088.

To all whom it may concern:

Be it known that 1, JOHN J. MARTIN, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in Railways, of which the following is a s ecification.

My invention has to do with railways and more particularly to modes of fixing railway rails with respect to their beds; and it contemplates the provision of a railway constructed in such manner that the rails are securely held against vertical and lateral movement and are uniformly supported throughout their length, thereby assuring a perfect continuous and uniform rolling surface for cars and eliminating the shocks and jars so frequently incidental to the movement of cars or trains.

The invention also contemplates providing a railway, designed especially for use in the streets of cities, and constructed with a view of being expeditiously and easily repaired, when the rails are worn or otherwise impaired, at a minimum cost and without entailing material if any injury to the pavement of a street.

The invention further contemplates the provision of railway rails of such construction that adequate provision is made for expansion and contraction of the rails, due to changes in temperature, and this without the objectionable creeping and the evils attendant thereon.

Other advantageous features peculiar to my novel railway construction will be fully understood from the following description and claims when the same are read in connection with the drawings, accompanying and forming part of this specification, in which:

Figure 1 is a plan view of a portion of a railway, constituting the best practical embodiment of my invention of which I am cognizant. Fig. 2 is a transverse section of thesame. Fig. 3 is an enlarged detail transverse section showing the relative arrangement of one of the rails and the holder and support thereof. trative of the intermediate portion of one of the rails comprised in my improvements.

Similar letters designate corresponding arts in all of the views of the drawings, reerring to which:

A is the bed of my novel railway, which is formed of plastic material, preferably con crete, and is designed, when the improve- Fig. 4 is a detail view illus-.

ments are used in a city, to be laid withits upper side flush with the surface of a avement. The said bed comprises spaced engitudinal and parallel portions a, and a plastic, preferably concrete, connection between the formed by transverse concrete portions 1), arranged at suitable intervals apart. and made inte ral or in a homogeneous mass with the longitudinal portions a.

B B are the rails of the improved railway, and C C are the rail-holders and supports, all of which are carried by and extend ongitudinally of the longitudinal bed portions 0. The rails B are peculiar in that the! are res ectivey made u of a head 0 an a web depen ing there rom; and the rail holders and sup orts 0 each comprise two longitudinal ang eirons e, spaced apart and embedded in alongitudinal portion a of the bed and held against 11 ward movement by the same.

It will e manifest by reference to Figs. 2 and 3 that the longitudinal bod portions it constitute durable and staple supports for the rail holders and an ports 0 and preclude casual movement of t e same in any direction, and that the holders and supports 0, in turn, serve, by reason of the arrangementof their upright parts directly under the heads of the rails, to adequatelv support and lend strengthto the rails, so that a solid and uniform surface is afforded ,for cars to travel upon, and one which admits of the meeting ends of the rails being op used to each other obliquely, as shown in i 1, or in any i other approved manner wit out liability of cidental to the passage of their wheels from one rail to the adjoining one. It will also be manifest that by reason of the rails being detachably connected by bolts D to their respective holders and supports, any rail when worn or otherwise impaired, may be expeditiously and easily removed and replaced by a new rail at a minimum cost, because of the small amount of steel in the rail, and without entailing material, if any injury, to the bed or the pavement in which the same is arranged. 5

the holders and supports C, to employ a lurality of the bolts D; and to provide eacli of the rail webs with a plurality of transverse apertures, the middle aperture of each series being preferably of circular form, and the two; the said connection being preferably,

the cars being subjected to shock and jar in- I prefer, in the connection of the rails B to.

1 others being rectangular in outline and gradually increased in length as they recede from the said circular aperture, as clearly shown in Fig. 4, As will be readily understood, the I provision just described is possessed of material advantage, inasmuch as it enables the rails to expan and contract in both direc tions equally and at the same time precludes thel obgectionable endwisc creeping of the m1 s.

With a view of precluding casual lateral movement or displacement of either of the rails and rail supports and holders, 1 provide I intervals in the length of the railway the l fir; r; :is E, one of which is clearly shown in Each of the said rods E is embedded ,n was of the transverse bed portions 1 and extends; through the upright portions of the rail orts and holders and is headed or other- P secured in a proved manner at the outer 2 r-a of the said olders and sup orts. From this will he understood that t e tie rods E rcinfor cc and strengthen the plastic bed and at the same time effectually prevent spread of the rails, and also prevent the imposi- 2 i i of pressure or strain on either of the longit idina bed portions (1, due to outward presr-inre exerted against the heads of the rails. it will also be observed that the tie-rods E eifect connection between the two angleirons e comprised in each holder and support 0.

it will be gathered from the foregoing that my novel railway is ossessed of strength and durability and is ca culated to afford a solid and uniform beari surface for an indefinite period; and that the initial cost of the improved railway is more than offset by the facility with which repairs may be made, and the fact that the removal of an impaired rail and the replacing of the same by a new rail 40 involves but a minimum loss in the cost of material, and does not entail material, if any, iniuryto' either the bed A or the avement in which the same is arranged, the am'aged rail being simply disconnected and lifted from between the upright portions of the holders and supports C, and the web of the new rail being l set ctween the said portions and fastened in l the manner shown snddescribed.

As before stated herein, the construction shown and described constitutes thebestpraci tical embodiment of my invention of which 1 am aware, but it is obvious that in the future practice of the invention such changes or modifications may be in ade as fairly fall within the scope of my invention asdefined in the clahns ap ended.

Having descri ed my invention, what I claim and desire to secure by Letters-Patl cut, is:

The combination in a 'ailway, of a plasably connecting the he bed. a rail holder and support permanently embedded in and held against movement by the bed and extending upwardly be end the upper side thereof, a rai having a sad bearing on the holder and support and also having a web extending downwardly into the same, and a bolt disposed above the bed and extending transversely through and detachortion of the holder and support, above the ed, and the web of the rai 2. The combination in a railway, of longitudinal plastic bed portions, a transverse plastic bed portion extending between and comprised in a homogeneous mass with the longitudinal bed portions, rail holders and supports permanently embedded in and hcld against movement by the longitudinal bed portions and extending upwardly beyond the upp er sides thereof, rails havmg heads bearing on the holders and supports and also having webs extending downwardlyinto the same, bolts disposed above the bed and extending transversely through and detachabl y connecting the ortions of the holders and su ports, above the bed, and the webs of the rails, and a transverse, metallic tie-rod disposed in and constituting a reinforcement for the transverse plastic bed portion and extending between and connecting the rail holders and supports.

3. The combination in a railway, of longitudinal plastic bed portions. a transverse plastic bed portion extending between and comprised in a homogeneous mass with the l0ngitudinal bed portions, rail holders and supports permanently embedded in and held against movement y the longitudinal bed portions and extending upwardly beyond the uppersides thereof and respectively comprising an gle irons separated by intervening spaces, rails having eads bearing on the holders and supports and also having webs extendin downwardly into the same, bolts disposed above the bed and extending transversely through and detachably connecting the portions of the holders and supports, above the bed, and the webs of the rails, and a trans verse, metallic tie-rod dis osed in and constituting a reinforcement or the transverse plastic bed portion andjconnccting the angle irons comprised in each holder and support and connecting the two holders and supports.

in testimony whereof I have hereunto set my hand in presence of two subscribing wit- 11 nesses.
